Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Ohmite 43F560E is determined by strict equivalence across the following parameters:

• Resistance value: 560 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 3W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Temperature coefficient: ±20ppm/°C (exact match required)
• Number of terminations: 2 (exact match required)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

The Riedon UB3C-560RF1 meets all mandatory electrical and mechanical parameters for direct substitution. Both components share identical core specifications and are suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the Ohmite 43F560E and Riedon UB3C-560RF1 are Active product status components with ROHS3 compliance and REACH Unaffected designation. Selection between these parts is based on availability, lead time, and physical space constraints. The Riedon UB3C-560RF1 features a more compact axial form factor (4.00mm x 8.90mm versus 5.60mm x 15.10mm) and includes additional functional attributes such as current sense capability, flame proof construction, moisture resistance, and pulse withstanding characteristics. Both components are suitable for direct substitution in applications requiring 560 Ohms ±1% 3W wirewound axial resistors.

Frequently Asked Questions (FAQ)

Q: Can the Riedon UB3C-560RF1 directly replace the Ohmite 43F560E?

A: Yes. Both components share identical electrical specifications (560 Ohms, ±1% tolerance, 3W power rating, ±20ppm/°C temperature coefficient) and axial package configuration with 2 terminations. Direct substitution is electrically and mechanically compatible.

Q: What are the physical dimension differences between these parts?

A: The Ohmite 43F560E measures 0.220" diameter x 0.594" length (5.60mm x 15.10mm). The Riedon UB3C-560RF1 measures 0.157" diameter x 0.350" length (4.00mm x 8.90mm). The Riedon component is more compact and may be preferred for space-constrained PCB layouts.

Q: Are both parts RoHS compliant?

A: Yes. Both the Ohmite 43F560E and Riedon UB3C-560RF1 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What additional features does the Riedon UB3C-560RF1 provide?

A: The Riedon UB3C-560RF1 includes current sense capability, flame proof construction, moisture resistance, and pulse withstanding characteristics. These features do not affect basic substitution compatibility but may provide additional performance benefits in specific applications.

Q: Are there any operating temperature limitations?

A: The Ohmite 43F560E operating temperature range is not specified in available documentation. The Riedon UB3C-560RF1 operates across -55°C to 250°C. For applications requiring extended temperature performance, the Riedon component provides documented thermal specifications.
